Hargobind Khorana shared the Nobel Prize in Medicine in 1968 for his work on interpreting the genetic code.

Hamilton Watch Company introduced the Pulsar in 1972, which was indeed the world's first electronic digital watch. This breakthrough marked the transition from mechanical to solid-state timekeeping, revolutionizing the watch industry with LED digital display technology.

Rado, not Rolex, introduced the Diastar in 1962 as the world's first scratchproof watch. The Diastar featured a revolutionary hardmetal case that was highly resistant to scratching. Rolex is famous for waterproof watches like the Oyster, but they did not create the Diastar.

Ingersoll produced the first Mickey Mouse watch in 1933 through a licensing agreement with Walt Disney Productions. This collaboration created one of the most successful character watches ever, costing under $3 and making wristwatches popular with children during the Great Depression.

Citizen Watch Company was originally founded as Shokosha Watch Research Institute in 1918 in Tokyo, Japan. The name was later changed to Citizen when the company adopted its current identity. 'Shakosha' appears to be a misspelling of Shokosha, but it's clearly the intended answer.

Casio introduced the first GPS watch in 1999 with the Casio GPS Pathfinder watch, which could determine location using satellite signals. This innovation allowed outdoor enthusiasts to track their position and navigate without separate GPS devices. Other companies followed later with GPS watches.

This statement is true. The average human skin hosts about 1 trillion microorganisms (bacteria, fungi, mites), while Earth's human population is approximately 8 billion. The skin microbiome is incredibly diverse and dense, with millions of microbes per square centimeter, especially in warm moist areas, making the total count vastly exceed all humans combined.

The statement is approximately correct. Average scalp hair count ranges from 100,000 to 150,000 strands, so the figure is accurate. Hair growth rate varies by individual (typically 0.3-0.4 inches monthly, totaling 3.6-4.8 inches annually), but 5 inches per year falls within normal variation. The statement captures the correct order of magnitude for both measurements, making it broadly true.

The statement is false as written. Astronauts actually become TALLER in space (up to 2-3 inches) due to spinal disc expansion in microgravity, not shorter. Upon return to Earth's gravity, this additional height is lost as the spine recompresses. The question reverses the actual phenomenon - they grow in space and shrink back to normal on Earth, not become shorter than they started.

This statement is false. While eyes reach near-adult size by childhood, ears and noses continue growing throughout life due to cartilage expansion and gravitational effects. This is why older adults appear to have larger noses and ears - they actually do grow slowly over decades. The only organ that truly stops growing early is the eye (specifically the eyeball), making the blanket statement incorrect.
